ALBERT K. WAYCOTT, 0F LJABCHMONT, NEW YORKV STEAM AND Warme VALVE Application led December 80, 1920. Serial4 No. 434,036..

To all lwlw/m, t may concern.'

B e it known that I, ALBERT K. WAYCQTT, a cltizen of the United States, residing in the village of Larchmont, county of Westchester, and State of New York, have invented a new and useful Improvement in a Steam and WatervValve, of which the following description, in connection with the accompanying drawings, is a specification, like :c aracters in the drawings representing likeparts.

This invention relates to water and steam valves, more particularly of the globe, angle and cross valve variety, and the object of the invention is to provide a valve of this kind having a removable combined liner and plug or gate housing, which can, be readily withdrawn for regrinding or replacement, when worn. i L

It not infrequently becomes necessary to regrind a lvalve or gate seat,l or otherwise repair the plug or gate housing in steam or water valves of the classabove referred to,

, and often in such cases, valves are located in 4such diilicult places of access, or where steam is employed the surroundings are so hot, that the work cannot be done without temporarily discontinuing the use of the connected steam or water pipes, or removing the valve itself.

In such circumstances with the kind of valves now in use, the makin of such repairs is laborious, diilicult an oftentimes dangerous.

With the use, however, of this invention,y

it is only necessary to unscrew the bonnet, withdraw the liner, which can be repaired at leisure, insert a new liner in its place, and attach the bonnet, which operation can ordinarily be effected in a few minutes time, and thus obviating the discontinuance of the use of steam or water pipes, for a considerable period, as is customary, under present equipment.

In the accompanying drawing showing an illustrative embodiment of this invention, and in which the same reference numerals refer to similar parts in the several figures, Fig.1 is a side elevation of a valve of this description, showing the removable body liner and main body assembly in section, the plug, disc vor gate being shown at the end of the spindle partially broken away for cleai-, ness, Fig. 2 is a horizontal cross sectional view taken on the line 2-2 (Fig. 1), Fig. 3 is an elevational perspective view of the removable liner, Fig. 4 is a side elevational view of the inner portion of the spindle with' opening at the end 4 to a point at or slightly below the lower edges of the openings 5, where it inclines inwardl uniformly, circumferentially forming a evelled,seat,6 for the plug or gate 9, and thencontinues uniformly to the end 3 the opening of which, therefore, is somewhat smaller than the opening at the end 4.

The interior of the body' 13 starting at the point 30 and extending downwardly and through the wall 23 is tapered circumferentially, to -correspond exactly with the outside surface 2 of the cylindrical linerl l and adapted to hold or retain it in a horizontal position so that the under surface of the end 3 is flush with theuncer -surface of the wall 23.

When the liner 1 is in place as inFig. 1, it is removably held in position by the lower end 21 of the bonnet 14, the sides of which end have runnin-g circumferentially, an external thread, adapted to play withm a similarly internally threaded openin 30 of the body 13, flanged portions 19 o the bonnet adapted for engaging and closing the openin 30.

The spin le 18 has a removable handwheel 17 at one end and a Hangs 22 at the opposite end, adapted to be swivelly or mova y secured within the plug or gate 9 by means of a threaded lock nut 29 and has a threaded portion 25 adapted to play within athreaded portion of the bonnet 24 for raising and lowerin the plug or gate 9 which is of cy lindrica formation and adapted to slidably move lengthwise in the liner 1 the sides 28 'in contact-with the wall of the bore 31 from the opening at vthe end 4 to the bevelled edge 6 upon which it is adapted te coe to rest when the gate is closed. The gate or plu 9 preferably has bevelled edges, circum erentially at both ends, 10 and 11, the bevelled. edge of the lower or bevelled edge of which 10, of like shape, is adapted to seat and fit within a similar in-YYY ternal bevelled end 8'of therbonnet 14 so that when the valve is openedY and the plug the spindle 18, it is fully enmeshed within the end of the bonnet and forms a seal against the escape of water or steam.

r[he area of each of the openings 5, in the liner 1, sslightly more than the area of the 'pipe connectlon openings, 26 and 27, to per- -mit an easy flow ofthe volume of water or steam.

,-Escapement of water or steam is prevented by the packing 2), confined by the follower orligland 16, which is held in place by the packing nut 15, the threaded portion of which 12, is lscrewed to and over the up er end -of the bonnet 14.

y swaging'the recessed Yend of the plug or gate 9, asin Fig. 4, allcwing some play, a simple method is afforded, of attaching the gate or plug to the end of the spindle.

Having described this invention in connection with the illustrative embodiment thereof to the :details Vof which disclosure the invention is not, of course, to be limited, what is claimed as new and what is desired to be secured by Letters Patent is set forth in the ap nded claims.

1. A va ve having a vertical tapered bor-Y ing or opening between opposite ports, a

tapered Y,liner with side openings therein,Y

2. A valve. having a vertical tapered borlng or openlng between opposite ports, a tapered liner adapted for insertion in the boring, having an opening therethrough lengthwise and two opposite side openings therein, internal annular gate seating means in one end of the liner, a slideable gate for play 1n the lengthwise opening adapted to engage said seating means for closing the liner, a spindle adapted for turnable connection with the gate member for actuating the same, a bonnet for holding the spindle member.

3. In combination, a valve body membe having a vertical tapered boring or opening between opposite ports, a tapered liner `adapted for insertion in the/valve body bor- Leanser in one end of the liner, a gate for cooperating with said seating means for closing the liner adapted for slideable engagement within the lengthwise peningof the liner, a spindle adapted for turnable connection with the gate member for actuating the i same, bonnet means for holding the spindle or gate 9 has been fully raised by means of member.
